PLANE.

SPECIFICATION forming part of Letters Patent No. 317,092, dated May 5,1885.

Applicationfiled September 2, 1884. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE A. CLIFFORD, of Peabody, in the county ofEssex, State of Massachusetts, have invented a certain new and usefulImprovement in Planes, of which the following is adescriptionsufficiently full, clear, and exact to enable any person skilled in theart or science to which said invention appertains to make and use thesame, refer- IO ence being had to the accompanying drawings, forming apart of this specification, in which- Figure 1 is an isometricalperspective view of my improved plane Fig. 2, a vertical 1ongitudinalsection of the same; Fig. 3, a Vertical transverse section; Fig. 4, abottom plan view Fig. 5, afront elevation of the iron and its stockdetached from the body;-Fig. 6, a vertical longitudinal section .of thesame, and Fig. 7 a vertical transverse section of the stock 7 with theiron removed.

Like letters of reference indicate corresponding parts in the differentfigures of the drawings.

My invention relates to the class of planes 2 5 known as chamfer-planes,and it consists in a novel construction and arrangements of the parts,as hereinafter more fully set forth and claimed, by which a moreeffective device of this character is produced than is now in ordinaryuse.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation, itsextreme simplicity rendering 3 5 an elaborate description unnecessary.

In the drawings, A represents the body, B the stock, and O D the irons.The body is provided on its under side with a longitudinal V-shapedequilateral groove, E, running its 0 entire length, and adapted to fitover or receive the corner or edge of the article to be chamfered orbeveled. An inclined mortise, H, for receiving the stock, is formed inthe body, and at the rear ofthis mortise, on

5 either side, there is disposed a slide or rest, as, against which thestock presses. The stock B isrectangular in shape, and is provided oneither side with a longitudinal dovetail groove, m. Each of its ends isinclined, as

shown at f, one of them being rounded, as

seen at t, and the other squared, as shown at '0. The stock is providedwith two irons, O D, disposed in a chamber or recess, J, which is cut inits face, as best seen in Figs. 1 and 6. The iron D is rounded on itscutting-edge 5 5 to correspond with the rounded end '5 of the stock B,the iron 0 being squared on its outting-edge to correspond with thesquare end '12 of said stock. A mouth, 2, opens outwardly from thechamber J through either end of 6c the stock B, the irons O Drespectively protruding through these mouths and being adjustablysecured to the stock by the screwbolts K.

Passing through either side of the body A, 6 5 opposite the mortise H,there is a bolt, r, provided at its inner end witha square head, t,adapted to fit the dovetail groove m in the stock B, the outer end ofsaid bolt being screw threaded and. respectively provided with nuts N.

In the use of my improvement the stock B is inserted in the mortise H,with the heads t of the bolts 1' in the grooves m where it may besecured in any desired position by turning in the nuts N. The loweriron. or iron to be used is then properly adjusted and secured by itsbolt K, the upper or idle iron being withdrawn into the chamber J, andalso secured by its bolt K.

It will be obvious that by reversing the stock B either iron may bebrought into use, and also that irons having any desired shape ofcutting edge or edges conforming to the style of work to be done may beemployed. 8 5

I do not confine myself to securing the stock in the body A by means ofthe bolts 9' and nuts N, as any other suitable means may be employed forthis purpose.

Having thus explained my invention, what I go pass througlrthe sides ofsaid body and take into nuts within said grooves, substantially I I intonuts within said grooves, substantially as as described.

3. The combination, in a bench-plane, of a described. body, a stockadjustable therein provided GEORGE A. CLIFFORD. 5 with T-shaped grooves,said stock being pro- Witnesses:
